n tioned for use with relation to a continuous frame in a commercial building, and another position being shown in Fig. 2 as best adapted for use on a window frame of a. dwelling and the like. I also provide a fourth mem ber 13 preferably in the form of an angleiron having a plurality of perforations 14:, the central perforation being adapted for fastening on said threaded bolt portion 5 by holding nut 6, or other suitable means, when used at cross-section with said member 1 when used on: commercial buildings, and the like, and the outer perforations for use in fastening said member 13 vertically with, relation to said member 1 when used on window frames .15., and the like." It will be observed in this connection said end perforations 14 are removed slightly from the ends for the purpose of giving bracing hold of said member 13 againstupstanding L-shaped lug 7..

In operation, it will be observed when ap- V plied to a window frame, or the like, as best shown in Fig. 2, member 13 is placed vertically with relation to member 1, its upper end fitting tightly against .lug 7 its lower end clamping tightly on the inside of the frame 15 and said member is held securely by bolt 5 and nut 6. Member 1 is positioned horizontallyhaving working boards or platform 16 resting on the top thereof and at right angles thereto; that members 8 and 10 are.

fastenedto perforations 2 in said member 1 intermediate its ends being fastened thereto bywinged bolts or nuts 9 and 11; that the other ends of said members 8 and 10 are fastened together by winged bolts or nut 12 theinlower ends being adapted to be secured against the outside of said frame 15..

In the operation of the device for use on buildings known as commercial buildings andlthe like Wherethere is a more or less continuous frame work of windows from top to bottom, member 13 is inserted from the outside through the openings in the metal frame work. This may be more easily done at times by loosening the nut 6 on bolt 5 and changing temporarily the angle of said mem-. ber 13 then by inserting same through said metal frame and turning member 13 so that it will be at right angles with both member 1 and member 8. Said member 13 will then be against the inside of at least two of the vertical metal frames 17. When desired said me ber 13 may be made of greater length for more bearing surfaces and for greater holding power. It will also be observed, that is claimed and desired to be secured-by Letmember 1 and said portions18. It is desired in suchuse that at least two of my devices shall be used for properly supporting the working board or platform 16. Said member 8 will be adaptedto'abut against at 'least two of such horizontal portions 18, and may,

if desired, be made longer to abut a greater number for more resistance power. 7 When so positioned nut 6 is securely tightened on threaded bolt5 of each of my devices so used, and the working board or platform 16 is then placed upon member 1. After said nut 6 is so positioned I prefer to have a lock washer or nut 6 placed on said bolt 5 for securely Said member 8 will under such cir- I.

holding said member together. The work of re-positioning same for work in another place is simple, by loosening said nut 6 on said threaded bolt5 and placing the device as has been above described. 1

The device can be easily packed and r so,

shipped by unfastening the winged bolts or nuts and placing the different members side by side and tying or otherwise fastening them together for shipment.

The member 1 being hereinbefore described as an L-shaped member may also be made in the form of a T-shaped angle iron. i

said second member having a central perfo-c ration adapted for transverse connectionvvith relation to one end of saidfirst member and adaptedto be held to said iirst member by said bolt and nut, an L-shaped upstanding lug secured to the reinforced end of said first member, said second'meniber and said upstanding lug adapted to hold said member securely and rigidly to a fixed portlon of a structure.

3. Adevice of the class'described, com

prising a first longitudinal L-shaped. angle iron member having perforations in one of its Webs and an upstanding hp at its'o'uter end adapted for holding and supporting a Working platform, and havingits other end re-inforced equipped with ascrew-threaded bolt ands-an. upstanding L-shaped lug member verse. L-shaped angle iron member having perforations, and adapted for fastening ata selected perforation on" said threaded bolt I end of said first member, a third L-shaped inclined angle iron member having perforations adjacent each end, one of its ends it adapted for pivotally fitting a selected one of said plurality of perforations in said first] Jmember, a fourth L-shaped vertical angle iron member having a perforation adjacent each end one of 1ts ends adapted to p1votally connect a selected one of said perforal tions in said first member and its other end adapted to pivotally connect the second end .fof'said third inclined member, said fourth vertical member and said second transverse member adapted for rigidly gripping the Window sill or frame of a building for securing, holding and supporting said first member and said working platform, said second transverse member adapted to be held to said threaded bolt end by a suitable nut and said nut adapted to be locked thereon by a suitable locking nut.
